JOHN SHIER, OF DETROIT, MICHIGAN, ASSIGNOR OF ONEJIHIRI) TO FRED- ERIOK LEADBEATER, OF SAME PLACE.

BICYCLE.

SPECIFICATION forming part of Letters Patent No. 453,514, dated June 2, 1891.

Application filed March 13, 1891. Serial No. 384,927. (No model.)

To @ZZ whom t may concern:

Be it known that I, JOHN SHIER, a citizen of the United States, residing at Detroit, countyof V'Vayne, State of Michigan, have invented a certain new and useful Improvement in Bicycles; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same,

1o reference being had to the accompanying drawings, which form a partof this specification.

In the drawings, Figure l is a side elevation of a bicycle embodying my invent-ion.

r 5 Fig. 2 is a perspective view of the framework without the wheels.

It is the purpose of my invention to improve a bicycle-frame whereby it is rendered of simpler and more effective construction, is

zo rendered more yielding and easy for the rider, its parts are not subj ectedto strains which are liable to derange the same or cause it to be wrenched or injured, and in other special features of construction, all of which are herein- 2 5 after more particularly described, and pointed out in the claims.

In carrying out my invention A, represents the yoke, which embraces the forward axle; B, the upright standard in which it is jourgo naled; C, the handle; D, the yoke embracing the rear axle, and F. a spring joining the top of the yoke D with the upper end of the standard.

F represents springs extending from the 3 5 lower end of the standard to the extremities of the rear axle.

G represents bracerods extending from the rear axle diagonally to the top Of the standard B.

4o The spring E and the braceaods Gare pivoted to the standard at their union therewith, and the springs F are likewise pivoted to the standard at their union therewith. The top spring E is likewise pivoted to the top of the yoke D.

II is the treadle-axle supported by the nprights H and braces H2, and the upper ends of the uprights Il' are pivoted to the seat frame J. This seat-frame J bears upon and 5o is engaged with the springs E and F.

K is the seat, made adjustable in the frame by a set-screw or equivalent K.

K2 is a movable block or support, to which the forward end of the seat-leather is attached, and this is made adjustable, so as to stretch the said leather, when desired, by a set` screw K3.

It is manifest thatthe brace and rods G, in conjunction with the lower springs F and the standard B, constitute a triangle, which main- 6o tains the upright always in its proper position, while at the same time the pivotal connections at e and f remove from these points of union any tendency to wrench or strain the parts as the springs flex up and down. Again, the seat resting upon the springs E and F, the springs yield readily and easily and make the implement a very easy rider. So, also, the pivotal connection at e with the rear yoke D permits an easy iiexing of the 7o parts at this point without any wrenching strain. Then, again, the frame H H2 being connected at h by a pivotal connection with the seat-frame J there is nobinding or wrenching of the parts at this point, as the springs E and F flex up and down, and the treadle-l axle is always maintained in its proper rela` tion to the axle of the rear-wheel and to the seat K.

A velocipede of this construction is exceed- 8o ingly simple. Any one of its parts if injured or broken can be easily replaced, and the whole device is rendered not only very effect ive but simple, inexpensive, and durable. It may be provided with any of the usual appliances for taking up wear at its journals and other wearing parts and for aligning the wheels, these features constituting no essential part of my invention.

An adj usting-screw 7c may be employed for 9o tilting the seat to any desired angle, the same being used in connection with the clips 7c.

The springs F may be engaged at their forward ends by any convenient pivotal mechanism; but I prefer that the standard B be formed with a lug l), having an eye, and that the springs be formed with corresponding eyes, so that one spring shall be bound upon one side ofthe lug l) and the other spring upon the other side ot the lug, and the whole be Ioo held together by'a common pivot-bolt. These pivoted connections may allbe provided with conical bolts, if desired, to take up Wear or lost motion, and this may be done at all the points e, e,f, and h, and like provision may be had at the pivot d, Where Ythe rearyoke is engaged adjacent to the rear axle.

The implement may or may not be provided With the usual guard L.

What I claim isl. In a Velocipede, the combination, with the standard B and the axle, of the yoke D,

brace-rods G, and springs-EF, and afseat F and brace-rods. G, said springs F adapted to receive and support the seat, said parts E, F, and G pivoted to the said standard, substantially as and for the purposes described.

4. The combination, with the standard, of the springs E-F and braces G, pivoted thereto, and the pedal-,framelikewise pivoted at h,sub stantially as and for the purposes described.

5. A Velocipede consisting of aforward and a rear Wheel, the yoke A, With its handles, standard B and yoke D, and in connection therewith the springs E F, braces G, a seat supportedonand` sustained thereby, and a treadle-supporting frame engaged with the seat-frame, substantially as and for the purposes described.

6. The combination, withth'estandard B, the springs E' F', and brace-rods G, offth'e yoke stantially as described.v
